To all whom it may 0011mm:

Be it known that l, Mosns DANKBERG, a citizen of the United States.residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements inMasticating-lilachines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which itappertains to make and use thesame, reference being had to the accompanying drawings, and to figuresof reference marked thereon, which form a part of this specification.

This invention relates to a masticating machine which is adapted to mashor beat material so that it becomes a pulp, being particularly adaptedfor the mashing of potatoes and similar vegetables whereby the operationis quickly done and large quantities can be mashed in a short space oftime, the machine being adapted for use in restaurants and similarsituations.

The invention is further designed to provide a machine of this typewhich is smooth running and which provided with a particularlul'iricating installation which insures the lubrication of the maindriving parts, but prevents any of the lubricant passing ito the casingitself so that none of the material being masticated will come incontact with any of the lubricant.

The invention is further designed to provide a machine which is easilycleaned, the masticating parts attached to the main shaft being easilyremovable and all of the parts being without minute crevices or smallprojections so that when the machine is taken apart each of theindividual portions can be cleaned thoroughly and quickly.

The invention is illustrated in the accompanying drawing, in which-Figure l is a vertical section of the machine with the masticatingportion in elevation, and Fig. 2 is a section on line 2, 2, in Fig. 1.

The device consists of a casing which is made in the form of a cylinderand is preferably cast in one piece and integral with the supports orlegs 11 and the hopper 12, the hopper providing means for feedingmaterial to the machine, the inlet formed by the hopper being located atone end of the machine and preferably at the top thereof.

On one end the casing is formed into a bearing 13 in which is rotatablyarranged the operating shaft 1% which can be rotated by any drivingmeans, but I prefer to employ the hand-wheel 15 having the handle 16thereon. The inner face of the bearing 13 is provided with a circularrecess 17 into which is adapted to be rotatably fitted the head 18 ofthe operating shaft 14;. These parts are permanently installed in themachine. The head 18 is provided with a recess 19, this recess beingadapted to receive a projection 20 on the end of the main shaft 21. Theprojection 20 and the recess 19 are so formed that they co-act so thatthey rotate in unison, this being preferably brought about by makingboth the recess and the head rectangular in shape, the preferred formbeing square. The inner face 22 of the end of the casing, exclusive ofthe recess 17, is made flat and receives the disk 23 which is attachedto the main shaft 21, the disk 23 rotating against the face 22 forpurposes to be hereinafter described.

The bearing 13 is provided with an oil cup or any other suitable sourceof lubrication supply 24 which feeds oil into the oil passage 25 so asto lubricate the operating shaft 14 and its bearings the passage 25 terminating in the lubricating channel 26 which has an outlet 27 passinginto the oil pipe 28 so that lubricating material in excess of thatrequired will pass down through the pipe 28. The lubricating materialwill pass around the head 18 in a sufficient quantity to lubricate itslightly and prevent its working hard, but any further spread of thelubricant is prevented by the fitting of the disk 28 against the face 22so that the lubricant is insured in its confinement to the bearing 13and does not pass within the cylinder 10 to come in contact with thematerial being mashed or masticated.

At the end of the casing opposite the bearing is an outlet plate 29. Thecasing is provided with lugs 30 in which is adapted to swing an eye 31of a bolt 32, each bolt being screw-threaded and being provided with anut 38 so that when the bolt 32 is swung between the lugs 34, which arearranged in pairs on each side of the outlet plate 29, the nut 33 can bescrewed up on the bolt 32 against the lugs 34, as shown in Fig. l, andthe outlet plate is locked in position. On its inner face the outletplate
